##################################
# NtripCaster configuration file #
################################################################################

############### Server Location and Resposible Person ##########################
# Server meta info with no fuctionality.

### 下記3行を変更したがローカル使用なので多分あまり影響しない。
location BKG                     →HOIHOIDOに変更
rp_email casteradmin@ifag.de     →自分のメールアドレスに変更
server_url http://caster.ifag.de →http://192.168.1.212に変更

########################### Server Limits ######################################
# Maximum number of simultaneous connections.

### 下記3行も気分的に変更した。
max_clients 100                  → 20
max_clients_per_source 100       → 20
max_sources 40                   → 8

######################### Server passwords #####################################
# The "encoder_password" is used from the sources to log in.

### パスワードを変更しておく。
encoder_password sesam01         → XXXXXXXX

#################### Server IP/port configuration ##############################
# The server_name specifies the hostname of the server and must not be set to
# an IP-adress. It is very important that server_name resolves to the IP-adress
# the server is running at.
# For every port, the server should listen to, a new port line can be added.

### 下記1行も変更したが、これもローカルだと意味なさそう。
server_name igs.ifag.de          →rtk.hoihoido.com
#port 80
port 2101

######################## Main Server Logfile ##################################
# logfile contains information about connections, warnings, errors etc.

logdir /usr/local/ntripcaster/logs
logfile ntripcaster.log

############################ Access Control ###################################
# Here you specify which users have access to which mountpoints,
# one line per mount.
#
# Syntax: /<MOUNTPOINT>:<USER1>:<PASSWORD1>,<USER2>:<PASSWORD2>,...,<USERn>:<PASSWORDn>
#
# /<MOUNTPOINT>: name of the mountpoint. Must start with a slash.
# <USERi>: name of the user that has access to <MOUNTPOINT>.
# <PASSWORDi>: password of <USERi>.
#

### たぶん、ここが一番大事
# example:
#/mount0:user0:pass0,user1:pass1,user2:pass2
#/BUCU0:user1:password1,user2:password2 → コメントアウト
#/PADO0                                 → コメントアウト
/HOIHOIDO                              → 追加
